SAW-SWAG l NG DEVICE.

SPECIFICATION forming part of Letters Patent No. 633,704, dated September 26, 1899.

Application filed January 20,1899. $811811 702,769. (No model.)

To all whom, it may concern/.-

Be it known that LDANIEL G. SCHLABACH, a

citizen of the United States, residing at Farinerst-own, in the county of Holmes and State of Ohio, have invented certain new and useful Improvements in Saw-S waging Devices; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon, in which Figured is a view showing the tooth to be swaged properly clamped and a swage in position to be brought down upon the tooth. Fig. 2 is a view showing the punch or die in proper position for use, also showing a tooth located between the clamping-blocks. Figs. 3 and at show a pair of clamping-blocks. Figs. 5 and 6 are similar views showing different positions of the tooth. Figs. 7, S, and 9 are views showing the different stages or degrees of making a saw-tooth.

The present invention has relation to sawswages; and it consists in the different parts and steps hereinafter described.

This invention has reference particularly to the making of saw-teeth that are to be inserted and held in proper position in the blade of a saw.

In the accompanying drawings, 1 and 2 represent the clamping blocks, which are securely clamped together by means of a vise, such as 3, or they may be clamped together in any other convenientand well-known manner. The block 1 is provided with the shoulder tand the anvi15. Above the shoulderiare located the grooves U, which grooves are for the purpose of receiving the saw-teeth, as illustrated in Figs. 5 and 6. The block 2 is also provided with grooves 7,which are formed upon the right-angle portion 8, which rightangle portion sets over the shoulder 4: when the blocks are brought into the position illustrated in Figs. 1 and 2, and the grooves 6 and 7 are brought opposite each other, so that they will hold a saw-tooth in firm position.

In use the die 9 is set onto the tooth designed to be swaged and struck with a hammer or like article, which process forces the metal into the position illustrated in the dotted lines, Fig. 7, and shown full in Fig. 8. After the tooth has thus been treated it is released and brought into the position illus trated in Figs. 2 and 6, after which the punch or die 10 is brought into the position illustrated in Fig. 2, it being understood that the blocks 1 and 2 are to be held in avise during this operation. The punch or die is struck a sufficient number of times to swage the metal located at the point 11, Fig. 8, toward the bottom of the tooth, therebybringing the surplus metal to the cutting-point of the tooth. After this has been done the tooth is removed and brought into its original position and again swaged by means of the die 9. This alternating operation is continued until the tooth has been given the proper amount or degree of swaging.

.It will be understood that the blocks 1 and 2 may be of any desired form and do not within themselves form any particular part of the present invention except as a means to properly hold the tooth designed to be operated upon.

It will be understood that the blocks 1 and 2 are to be provided with various shaped grooves, such as (Sand 7, said grooves being formed to correspond with the form of the tooth designed to be operated upon. It will also be understood that by providing an anvil, such as 5, the block 1 will form one of the tools designed for use in swaging the teeth of saws.

It will be understood that by my peculiar process the teeth of saws are operated upon in such a manner that no metal is lost and that by alternating the operations the metal heretofore cut away from filing or otherwise is saved.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of clamping-blocks provided with grooves for an insertible saw tooth, and one of said blocks provided with an anvil, and tools for alternately upsetting the cutting end of a tooth While clamped in one of said grooves, and spreading the end thereof while clamped in the other groove, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

DANIEL O. SOHLABAOH.
